SITE.su is an online marketplace specializing in premium domain names, with a catalog of more than 40,000 domains across the .ru, .su, and .рф zones. The platform helps businesses and individuals find keyword-rich names for websites, brands, and online projects. Customers can browse available domains, search by words or other parameters, and review related options such as synonyms, translations, and transliterations. Listings include purchase and monthly rental prices, with additional information such as domain age and selected ranking or search metrics.

SITE.su offers two main ways to use a domain: instant online purchase, with the domain transferred to the buyer, or rental by assigning the customer’s DNS servers. Rental agreements can include a guaranteed right to buy the domain later. The website also provides downloadable domain lists, account registration and sign-in, an online help section, and a contact form for questions or price offers. Its services are designed to make domain discovery and acquisition straightforward, whether customers are seeking a specific name or exploring a broad selection.
